SYNOPSIS

DESCRIPTION

12       This  manual page documents briefly the spacechart and This manual page
13       was written for the Debian GNU/Linux distribution because the  original
14       program does not have a manual page.
15
16       spacechart  can  be  used to display maps of the stars in 3D and rotate
17       them.  It is capable of showing only a subset of the stars in  a  given
18       data  file, and only those within a given distance of the center of the
19       display. Also, it shows lines between stars  that  are  closer  than  a
20       given distance.
21
22       Open  a  data file with the 'File/Open' menu item of the 'Open' toolbar
23       menu. A map of the stars in the data file should  appear  in  the  main
24       window.  You can rotate it by moving the mouse across it with the right
25       button pressed.
26
27
28       The 'View Radius' scrollbar allows you to select which is  the  maximum
29       distance  from  the  center  star you want to see. The 'Zoom' scrollbar
30       magnifies the center of the image.
31
32
33       The "User Coords" are  the  ecliptic  latitude  and  longitude  of  the
34       observer,  and  a  "North"  parameter  that  indicates which way of the
35       screen is north. So, if the "north" field is 0, north  is  towards  the
36       top  of  the  screen, and if it is 180, it's towards the bottom. If you
37       change the user coordinates by hand, you will probably use only "round"
38       values of "north".

41       If you click on a star a dialog will pop up showing the info about that
42       star system. This dialog allows you to center the display on that star.
43
44
45       The 'Max Link Shown' field select the  maximum  size  for  which  links
46       between  the  stars  will  be  shown.  How these links are drawn can be
47       selected in the 'Links' page of the settings.
48
49
50       The star selection dialog allows you to select a subset of the stars to
51       be  shown  according to their luminosity, spectral class and multiplic‐
52       ity.
